Question 1

The ability of a telescope to see details is called _______.&#10;A) resolution&#10;B) focus&#10;C) aperture&#10;D) pixel

Accepted Answer

Resolution is the term used to describe a telescope's ability to see details, distinguishing between objects that are close together in the sky.

Question 2

The surface of the CCD is covered by thousands of small _____.&#10;A) silicon nodules&#10;B) photocells&#10;C) cones&#10;D) pixels

Accepted Answer

A CCD (charge-coupled device) is an electronic device that converts light into an electrical signal. The surface of the CCD is covered by thousands of small pixels, each of which is a photocell that converts light into an electrical charge.

Question 3

The Crab Nebula is the remnant of a supernova that was visible in&#10;A) 1054 CE&#10;B) 1054 BCE&#10;C) 1954 CE&#10;D) 100,000 BCE

Accepted Answer

The Crab Nebula is the remnant of a supernova that was observed on Earth in 1054 CE. Historical records, particularly from Chinese astronomers, document the appearance of a new bright star in the sky during this time.

Question 4

The size of the telescope is called its _________.

Accepted Answer

The answer of The size of the telescope is called...

Question 5

A way to show nonvisible wavelengths that takes advantage of your eyes' ability to discern color difference is called _________.

Accepted Answer

The answer of A way to show nonvisible wavelengths that...

Question 6

The focus is where the light is concentrated.

Accepted Answer

The focus in optics refers to the point where light rays converge or diverge from, and it is typically where the light is most concentrated.

Question 7

The photoelectric effect is how the CCD works.

Accepted Answer

The photoelectric effect is fundamental to the operation of Charge-Coupled Devices (CCDs), as these devices convert incoming photons into electrical charges through the photoelectric effect.
